WINDOW-SWINGING DEVICE.

SPECIFICATION forming part of Letters Patent No. 643,750, dated February 20, 1900.

Application filed August 28, 1899. Serial No. 728,682. (No model.)

To all whom it may concern:

Be it known that I, GEORGE H. PARKER, a citizen of the United States, and a resident of Boston, county of Suffolk, and State of Massachusetts,,have invented certain new and useful Improvements in Window-Swinging Devices, of which the following is a full, clear, and exact description.

This invention is in the line of devices adapted for temporary application to an ordinary non-swinging window-sash for the purpose of enabling the same to be swung inward and be thereby held in a convenient position for its cleansing or for the resetting of a new pane of glass. One defect found in present devices of this character consists in the great liability of the window-sash becoming dislodged from its swinging device, and hence falling to the floor and being broken, at the same time seriously endangering the person who may be cleaning or repairing the same. To remedy this defect and at the same time to construct a windowswinging device which shall be simple, durable, and attractive in appearance is the object of this invention.

Referring to the drawings forming part of this specification, Figure l is a vertical central section of my windowswinging device, showing the same in its condition of application to a window-sash. Fig. 2 is a perspective view of one pair of the hinge members thereof, showing the relative positions of the two parts of such pair when in condition to be applied to the window. Fig. 3 is a similar view, but showing said parts turned relative one to the other as they will be when the window has been swung open thereon; and Fig. 4 is a plan View of the hinge members, showing the window-sash and windowframe.

The hinge members are arranged in pairs, one pair for the upper part of the windowsash and the other for the lower part, with a rodjoining them. They are preferably formed cylindrical in outline, as shown in Fig. 4, and each is made with a rabbeted or dovetail slot in its periphery extending from top to bottom thereof and a similar slot extending but part way. The long slots are provided for the purpose of admitting into the partial slots the headed pins by which the hinge members are attached to the window frame and sash, after the hinge members have been turned one relative to the other, the unbroken part of each hinge member closing over the partial slots and locking them from permitting said pins to be withdrawn.

Referring to the drawings, the hinge member 1 is shown provided with the open slot 12 and the partial slot or notch 11, while the hinge member 2 is formed with the slot 22 and the notch 21. When these hinge members are so positioned as to bring the said slots in alinement with said notches, as in Fig. 2, said notches can receive the headed pins 9'; but when either member is turned, as shown in Fig. 3, said notches are closed.

As indicated in Fig. 1, the two pairs of hinge members are united by the vertical rod 3, which is made long enough to locate said pairs one near the upper part of an ordinary Window-sash and the other near the lower edge. In each pair of the hinge members one thereof is fixed upon the rod 3 and the other rotative thereon. Preferably the upper member 1 is thus fixed to the rod, while the mem ber 2 is loose thereon, being kept from longitudinal displacement thereon by means of the fixed member above it and a fixed collar or shoulder 4 below.

In using this window-swinging device it is customary to furnish all the windows of the building with a set of the headed pins 9, two for each Window and two for the window-jamb of each window. These headed pins are permanently secured in both the windows and jambs and in the relative positions indicated in Figs. 1 and 4. It is of course necessary to locate these headed pins exactly the same in all the windows of the building in order that the single device can fit each of them in turn. To apply the device to any window thus prepared for it, the hinge members are first turned until the slots and notches 11 12 and 21 22 are in exact alinement. Then the window-sash is raised an inch or two to free it from the window-sill, the stop-bead 7 at the side of the window opposite to the swinging device is removed, the slots and notches ll 12 of the two pairs of hinge members are engaged with the pin-s 0 of the'window-jamb, and then the window-sash is lowered until its headed pins 9 enter the slots and' notches 21 22 of the hinge members. The window-sash can now be swung around into the room, turning upon the hinge members, and when thus turned the slots of said hinge members are brought out of alinement with the notches thereof, and hence lock said headed pins. Being thus locked in place, it is impossible for said pins to slip out of engagement with the hinge members, and hence impossible for the window-sash to become unhinged through any accidental upward pressure thereof. It is therefore possible to clean the Window or to reset any broken glass therein without the slightest danger thereto or to the individual manipulating the same.

lVhatIclaim as my invention, and for which I desire Letters Patent, is as follows, to wit:

1. In a window-swinging device, the combination of the two hinge members adapted to be turned one relative to the other, with their approximate faces in substantial contact, and said faces having the notches opening therefrom; the headed pins adapted to be engaged by said notches; and means for permitting the entrance of said headed pins into said notches before being locked therein by said turn of the hinge members, substantially as set forth.

2. In a window-swinging device, the combination with the headed pins, of the hinge members adapted to be turned one relative to the other with the approximate faces in contact, and formed with the vertical slots and notches adapted to be put in alinement and out of alinement in the manner and for the purpose set forth.

3. In a window-swinging device, the combination of the rod, and the two pairs of hinge members mounted thereon, each of said hinge members being formed with the slot and the notch adapted to coact with each other in the manner and for the purpose set forth.

4. In a window-swinging device, the combination of the rod, the two hinge members fixed on said rod, and the two hinge members loosely mounted on said rod; a fixed and a loose hinge member constituting a pair, and one of said pair being located near the upper end of said rod, and the other near the lower end; and each of said hinge members being formed with a slot and a notch, all of which slots are adapted to be put in alinement with all of said notches sii'nultaneously, substantially as set forth.

In testimony that I claim the foregoing invention I have hereunto set my hand this 21st day of August, 1899.

GEORGE II. PARKER.
